Cold air is entering the region, above the 800m tree line there is cornice and snowdrift development on leeward slopes. There is possibility of surface avalanches fracturing on 18 Mar layer, about 30cm depth, on upper steep areas of knoll and cornice slopes. The wind is starting to drop and snowdrifts are stabilising, although take care in the morning. A slope that was good yesterday might not be good today.

The risk of full depth avalanches is still high. To avoid an accident please change your habit of riding in the valley bottoms. The mountain is obviously heading into spring now with repeated freeze thaw cycles. Powder isn’t Niseko's only attraction, corn snow season is coming. Today expect dust on crust, be careful hitting trees. Have a good day.
